RUNNING-GEAR FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 459,157, datedSeptember 8, 1891.

ilAPplication filed August 15, 1889. Renewed February 11, 1891- SerialNo. 381,030. (No model.)

To aZZ whom it may concern.-

Be it known that I, TARGE G. MANDT, a citizen of the United States, anda resident of Stoughton, in the county of Dane and State 'of Visconsin,have invented certain new and useful Improvements in Running-Gears forVehicles; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to improvements in vehicle running-gears; and theobject of the invention is the production of durable, eifective, andinexpensive means for supporting and guiding the bolster-springs, forretaining the standards in place and allowing of their removal, andforguiding the body-supporting bar.

To attain the desired objects the invention consists of a metallic yokehaving such extensions or wings for supporting and guiding the springs;further, in an improved metallic yoke having side extensions forsupporting and guiding the springs, a recess in the upper portion toreceive the standard, and a supporting-bar having plates at each endformed with keeps adapted to guide said bar on the standards; and,finally, the invention consists in the construction, combination, andarrangement of parts illustrated, described, and specifically claimedherein.

Figure 1 represents a perspective view of the portion of a running-gearembodying my invention. Fig. 2 represents a top plan view thereof. Fig.3 represents aperspective view of the casting and standards 011 an enlarged scale.

Referring byletter to the drawings, in which similar letters ofreference denote corresponding parts in the said figures, A designatesthe bolster; B, the springs; C, the body-supporting bars, and l) theplates secured to the ends of the bars, having keeps or recesses Fdesignates a metallic yoke secured on the bolster near the end thereofand adapted to einbrace'it, as shown in Fig. 1. This yoke is providedwith the side extensions F having lugs F adapted to support and guidethe ends of the springs, and the ridge or flange F in the upper face oftheyoke, forming a socket or recess to receive the rib or flangeG on thestandard G.

The standard and yoke are secured to the bolster by means of bolts HandII, although the bolt H may be dispensed with and the single bolt ll beemployed for this purpose.

From the foregoing description, taken in connection with thedrawings,the operation and advantages of my device will be readilyunderstood, and, briefly stated, are as follows: The yoke is of a singlepiece of metal, and is so formed that while it rests on the end of thebolster it at the same time strengthens it, for by extending down thesides of the bolster it acts as a band or ferrule and preventssplitting. This yoke may be cast, stamped, or manufactured by any otherprocess. The kind or pattern of wagon to which it is to be applied willusually determine the process and material of manufacture. This yokebeing symmetrical as to its two sides and the springs being arranged inpairs, all tendency to strain the bolster by twisting or rocking isobviated. It will be seen thatthe springs are securely retained by thelugs F and at the same time they slide with perfect freedom on theextension F and may be removed or applied wi th the greatest facility.Certain other substantial advantages are also obtained by thearrangement of parts in this device. The yoke is entirely out of the wayof the box, and the springs and supporting-bars E being placed each sideof the bolster the box can drop down to the bolster when the load is tooheavy for the springs to support and there have a smooth surface to restupon. In devices where there is a rocking yoke having the springs fixedto the ends the yoke and its bearings mustnecessarily be inside thestandards and be in the way of the box when heavily loaded. it will beperfectly practicablc in my device to cut away the top of the bolsterslightly, if found desirable, to allow even thin plate I) to drop flushwith the top of the bolster. By the arrangement in my device thebearings of the springs are placed farther out than in other devices ofthis class. Therebyl amenabled to use a longer and hence easier spring.Moreover, experience has demonstrated that a spring of this class isless liable to break when the ends are free to slide than when the endsare bent around a link, rocking rod, or other similar attachment. Thisis doubtless partly due to the fact that by this arrangement the morethe spring is loaded the farther the ends slide out, and hence thesupports are relatively nearer the cutter of the spring and under itsthicker portions. It will be seen that this advantage cannot be gainedby any rocking yoke, for with a rocking yoke the heavier the load thefarther the points of support are actually moved from the center of thespring. It will also be seen that in my device the box or wagon-body canbe made to rest lower than when the spring rests upon the bolster.

The advantages and merits of my improvements will be readily understood,as I provide means for supporting and guiding the springs for retainingthe standards in place and guiding the body-supporting bar, whichpossess superiority over other devices in simplicity, durability,cheapness, and efficiency.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States 1. A running-gear consisting of theaxle, the castings at the ends of the bolster having the side extensionsand flanges forming sockets, the standards fitting in said sockets, thebars having the plates guided on the standards, and the springs securedto the bars and having their free ends bearing in the extensions of thecastings, substantially as described.

2. The herein-described yoke adapted to be rigidly attached to the endof awagonbolster beneath the standard and extend down its sides,substantially as shown, having extensions F and upwardly-projecting lugsF forming ways adapted to receive the sliding ends of half-ellipticsprings arranged in pairs, substantially as set forth.

In a running-gear, the combination of the bolster, a yoke F, havingextensions F lugs F flange F a standard having rib G, and the bolts Hand II, said yoke being adapted to support the sliding ends ofhalfelliptic springs, substantially as shown.

4. The combination, in a running-gear, of a bolster, yokes adapted to berigidly fixed t0. the ends of said bolsters, standards adapted to befixed on said yokes, half-elliptic springs arranged in pairs, one oneach side of said bolster and adapted to have their ends slide onextensions of said yokes, and body-supporting bars, all constructed andarranged to co-operate substantially as described.

5. The combination, in a running-gear, of the bolster, okes rigidlyfixed on the ends of said bolster, standards fixed in recesses of saidyokes, half-elliptic springs adapted to have their ends slide onextensions of said yokes, body-s11 pporting bars, and plates connectingsaid supporting-bars and having recesses or keeps adapted topreventlongitudinal rocking of the bars and springs, all constructed andcombined to co-operate substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
